Andreeva adds, "It is unclear whether they could make guest appearances in the future."

The story also notes that "Ferrer and Charles, along with Camilla Luddington and Jerikka Hinton, joined ABC‘s ‘Grey’s Anatomy’ as recurring last season, playing new interns. All four got promoted to regular heading into the current 10th season of the medical drama, which is poised to return next fall after stars Ellen Pompeo and Patrick Dempsey inked new deals to continue on the show."

The current season will also be the last for Oh, one of the original cast members, the report notes.
